An unconformity is a ______ of rock.
Sand dunes are formed by _____.
volcanoes
erosion
convergent faults
divergent faults
Answer: erosion
Erosion is the process of removal and displacement of surface soil particles by the effect of wind, water or chemical agent. The sediments due to the effect of these agents gets displaced to locations other than the one where their parent rock or soil originated. A sand dune can be defined as the accumulation of grained sized sand into the shape of ridge by the effect of wind under the influence of gravitational force exerted by the earth. Dunes are formed when the loose sand is blown by wind. Therefore, sand dune is the erosion of sand by wind. Sand dunes are formed in deserts, beaches, barren fields and semiarid regions.
A car travels a total of 400,000 meters. How many kilometers did the car travel?
A) 0.4
B) 4
C) 400
D) 4,000
Answer:
C)
Explanation:
400 kilometers the car traveled.
1 km = a 1000 mt. So, with that in mind, 400,000 meters is equal to 400 kilometers.
400,000/1000 = 400

Due to the increase in global temperatures, the range of plants and insects is increasing. The negative impact is that they now affect the local organisms in the area and are referred to as ______ species.
Plants and insects expanding into new regions due to global temperature increases are known as Invasive Species. This can upset local ecosystems, such as causing a mismatch in timing between when plants bloom and when their insect pollinators emerge. The impacts of these species can be negative for local organisms.
Explanation:Due to the increase in global temperatures, the range of both plants and insects is expanding, introducing them to new regions. This phenomenon can have negative impacts on local organisms as they compete with or be preyed upon by these new arrivals. The term for these new arrivals is Invasive Species. As a result of global climate change, these species are able to inhabit regions which were previously inhospitable, affecting the local ecosystems and organisms. An example of this can be seen where warmer temperatures have allowed plants to bloom earlier, but if their insect pollinators aren't also emerging earlier, it creates a mismatch in timing which could lead to negative impacts on the ecosystem. This is because in order for these plants to continue to survive, they must flower when their pollinators are present.

Due to the increase in global temperatures, the range of plants and insects is increasing. The negative impact is that they now affect the local organisms in the area and are referred to as invasive species.
Explanation:The term you're looking for is "invasive species." As global temperatures rise, there is an observed expansion in the ranges of certain plants and insects. These organisms can have a negative impact on local ecosystems as they outcompete native species, disrupt food chains, and modify habitats. Invasive species may also contribute to the decline of native organisms due to changes in phenology, the timing of lifecycle events like flowering and pollination.
The increase in global temperatures affects abiotic conditions, such as temperature and precipitation, which in turn influences the phenology of plants and animals. Earlier flowering times in plants and changes in the life cycles of insects can lead to mismatches in pollination times, potentially causing ecosystem disruption. Additionally, the spread of disease-carrying insects can bring about new health challenges as warmer climates allow these pests to expand their range and accelerate their breeding.
More broadly, climate change not only leads to direct changes in species distributions, but also to indirect effects such as increased competition among species, altering mutualistic relationships such as pollination, and changes in herbivory and seed predation rates. These factors contribute to the complex ways in which ecosystems are being reshaped by the increase in global temperatures, emphasizing the need for careful management and conservation efforts.

*density
8. The vertical drop of a stream channel over a certain distance is called _____.
*discharge
*channel roughness
*gradient
*runoff
Mass movements are driven by gravity and can range from slow creeps to rapid landslides. The key factors in these phenomena are the steepness of slopes, type of material, and climate. The eroding and transporting power of a stream depends on its velocity, and the gradient defines the stream's vertical drop.
Explanation:The force behind mass movements is, indeed, gravity. Mass movements always trend downslope due to the gravitational force. However, it's not accurate to say mass movements always lead to landslides; they vary in speed and scale. They could be a slow creep or a rapid avalanche.
Oversteepened slopes often lead to mass movements due to their angle being greater than 40 degrees. A block of material moving downslope along a curved surface is commonly referred to as a slump.
A rapid form of mass movement common in dry mountainous regions is rockfall. Water balances in the world environment are maintained since the average annual precipitation worldwide must match the quantity of water evaporated. The power of a stream to erode and transport material mainly depends on its velocity, rather than its width or length.
The vertical drop of a stream channel over a preset distance is described as its gradient.

How is renewable fuel use expected to change in the next decade?
please anyone?
True or False. Wind blows due to the differential heating of earth's surface.
True
False
Heat's effect on the wind cycle is most easily observed near the sea. During the day, the ocean absorbs heat from the surface, keeping the air above it cooler than above the land. When the warm air rises from the shore, the cooler air from the ocean blows in to take its place. At night, the land cools quickly, while the ocean radiates the heat it absorbed, keeping the air above warm. This reverses the effect, causing the air offshore to rise and creating a breeze from the land. Uneven heating can also occur due geographical features. A mountainside exposed to the sun will warm more than a shadowed valley below it, creating a wind that blows uphill during the day and downhill at night.
The same principle is responsible for global wind patterns. The polar regions receive less solar radiation than areas near the equator, resulting in a global shift in temperature according to latitude. This, along with differences in temperature and density in various layers of the atmosphere, creates global wind patterns like the jet stream that help drive weather systems.

The process of a parent cell dividing into a large number of genetically identical cells all at once is known as _____ .
Final answer:
The process where a cell divides into many genetically identical cells all at once is called multiple fission, while mitosis refers to the division producing two identical daughter cells.
Explanation:
The process of a parent cell dividing into a large number of genetically identical cells all at once is known as multiple fission. While the cell division in somatic cells, where a parent cell divides to produce two genetically identical daughter cells, is called mitosis, the process of multiple fission can produce more than two daughter cells. It is a form of asexual reproduction observed among protists and other single-celled organisms. However, binary fission is another type of cell division typical in prokaryotic organisms like bacteria, where the parent cell splits into two daughter cells. Despite the difference in the number of cells produced, both binary fission and multiple fission result in offspring that are genetically identical to the parent.

Cathy hypothesized that corn would not grow in mud. To test this hypothesis, she took corn kernels and placed 5 in mud, 3 in soil, and 2 in water. To her surprise, the kernels in the mud grew faster than the kernels in the soil. What error might have caused these unexpected results?
The unexpected results could be due to a disparity in sample size, varying environmental conditions or potentially flawed methods of measurement. Solution: Equalize sample size, ensure consistent conditions, and be clear on what 'growth' means.
Explanation:The unexpected results in Cathy's experiment could be due to several possible errors. First, sample size is a critical factor in any experiment. Cathy put 5 kernels in mud, but only 3 in soil and 2 in water. This imbalance could have skewed the results. Another potential error could be in the environmental conditions. Each type of medium (mud, soil, water) may have different characteristics like nutrient content, moisture level, and exposure to sunlight, which may have influenced the growth of the corn. Furthermore, Cathy's method of measurement could have an impact on the results, depending on how she defined 'growth'. For the future, Cathy should ensure that all conditions are consistent across all groups, except for the one variable she is testing, and increase her sample size. In this case, it would mean planting the same number of seeds in each medium and maintaining similar conditions like sunlight and temperature for all groups.

Water is unusual because it expands as it freezes. Very few substances have this property. The reason liquid water is more dense then ice can be best explained by? A) water is the universal solvent. B) Water has an unusually high boiling point. C) Water contains elements that are not common in other substances. D) Water is polar and the positive and negative ends of the molecule attract each other.
The correct answer is option D) Water is polar and the positive and negative ends of the molecule attract each other.
The water is a polar molecule, and forms a hydrogen bonding with the other water molecule. In the liquid state, the molecules of the water is in random motion, and the bond between the water molecules are continuously formed and deformed.
In the ice, the hydrogen bond between the water molecules become more stable, due to this, the molecules arrange themselves in a hexagonal pattern. Due to this arrangement, the allover space occupied is expanded. Hence, the ice is expanded than liquid water.
